University of Colorado Denver (CU) professor and architect Julee Herdt, in collaboration with John Hunt of the Forest Products Laboratory (FPL), and Kellen Schauermann, architect, CU alumnus and research assistant, recently received a patent for environmental construction materials.
BioSIPs structural panels for wall, floor, and roof constructions.
The patent includes software and material science for converting 100 percent waste fibers, such as post-consumer wastepaper, agriculture residues, flowers, hemp, wood scraps, noxious weeds, dead trees, and other unwanted cellulose, into high-strength construction boards. Using the technology, these dense yet lightweight and strong boards are bent and flexed into a virtually limitless array of shapes, from flat to complex, for making energy-efficient, non-off-gassing building materials, and buildings. The software also allows for associated manufacturing, economic, and recycling scenarios to be studied while the waste fiber eco-products are being designed. Continue reading
Research at the Forest Products Laboratory includes developing products and processes that impact people’s daily lives. But to bridge the gap between research results and real-world use, these technologies must be made available to private companies through technology transfer efforts.
The Ring Profiler is a patented invention that provides a more accurate look at how trees grow. It is available for licensing.
Patenting technologies is one way to encourage the commercial adoption of advances made at the Lab.
Patenting an invention excludes others from making, using, or selling the invention for a number of years. Securing a patent then enables FPL to grant patent licenses to private companies for use in commercial markets.
Technologies invented by FPL and other Forest Service scientists are available for licensing and/or cooperative research opportunities in the following areas:
– Field-ready Instrumentation Devices
– Firefighting Equipment
– Forest Insect Technologies
– Forest Products Utilization
– Fungal Remediation of Preservative Treated Wood
– Non-destructive Evaluation
– Pulp and Paper
– Wood Connectors
– Wood Preservation

A patent titled “Method and Apparatus for Determining the Surface Area of a Threaded Fastener” was recently awarded to FPL researchers Douglas Rammer and Samuel Zelinka. The invention is a method for reliably determining the surface areas of threaded fasteners, such as wood screws, drywall screws, or threaded nails.
The method entails acquiring an image of the fastener, separating the image into three regions (thread region, root region, and body surface), determining the surface area of each region, and summing them. The ability to determine this measurement is important for several applications, including studying the corrosion rate of fasteners.
